CROSS REFERENCE TO RELATED APPLICATION

This application claims priority under 35 U.S.C. §120 to and is adivisional application of U.S. patent application Ser. No. 12/889,032,filed on Sep. 23, 2010, hereby incorporated herein by reference in itsentirety.

FIELD OF THE INVENTION

The invention is related to a multi-purpose catheter that is used todeliver dose, measure the dose and remove human waste while providing aneasy connection module.

BACKGROUND

In medicine, a catheter is a tube that can be inserted into a bodycavity, duct, or vessel. Catheters thereby allow drainage, injection offluids, or access by surgical instruments. The process of inserting acatheter is catheterization. In most uses, a catheter is a thin,flexible tube (“soft” catheter), though in some uses, it is a larger,solid (“hard”) catheter. A catheter left inside the body, eithertemporarily or permanently, may be referred to as an indwellingcatheter. A permanently inserted catheter may be referred to as apermcath.

The ancient Syrians created catheters from reeds. “Katheter—

” originally referred to an instrument that was inserted such as a plug.The word “katheter” in turn came from “kathiemai—καθíεμα

” meaning “to sit”. The ancient Greeks inserted a hollow metal tubethrough the urethra into the bladder to empty it and the tube came to beknown as a “katheter”.

Prior catheters were used only for single functions, such as removinghuman remains and enlarging an area inside the human body. The singlefunctioning catheters require that medical personnel remove one catheterand insert another catheter into the patient when multiple functions arerequired to be performed on the patient. This removal and insertionprocess creates much discomfort to the patient, because the removal ofone catheter and insertion of another catheter creates pain. Also, whenmultiple catheters need to be inserted into a patient, each catheter isinserted into the patient. However, the catheter's excessive length cancause confusion and the medical personnel may perform a function on thewrong catheter.

Thus, the need exists to have a catheter that can provide multiplefunctions and which is less traumatic than current procedures involvinginsertion and removal. The present invention meets that need without therisk of causing damage or producing pain.

SUMMARY OF THE INVENTION

According to one general aspect, there is a medical device including alocking mechanism that is used to connect a plurality of catheters, amulti-balloon inflator that inflates multiple balloons on a singlecatheter, an extraction point used to remove bodily fluids, e.g. humanfluids from the human body, and a connecting point that allows a syringeor a machine to insert air or a liquid, such as a liquid salinesolution, or to insert radioactive isotopes into the multi-ballooninflator. Also, a multi-balloon catheter for medical applications isprovided that includes a multi-balloon inflator that inflates multipleballoons on a single catheter, an extraction point used to remove humanfluids from the human body, and a connecting point that allows a syringeor a machine to insert air or any other liquid, such as a liquid salinesolution, for inflation of a corresponding balloon of the multipleballoons. By allowing each balloon to have its respective connection, anadvantage of such connection is that it will allow medical personnel tocontrol the size of each balloon independently. Further, by havingmultiple balloons on a single catheter the shape of each balloon can bechanged relative to the location of the catheter in the human body toallow for a proper fixture, such as in a body cavity.

The medical device that contains the locking mechanism can be affixed toany male or female connection attached to any type of catheter.

The medical device of the multi-balloon catheter that contains themulti-balloon inflator is connected to each individual connecting pointto allow a volume for inflation.

The medical device that contains the said locking mechanism when affixedto another catheter creates a vacuum seal that does not allow the fluidsor any air to pass through any said connecting point.

The medical device that contains the extraction point contains an innerseal within the opening that only allows for a single direction flow foronly removal of fluids which does not allow for fluids to be insertedinto the human body.

The medical device that contains the extraction point is large enough tocontain a measuring device used to measure the amount of dose radiatedto human tissue while said extraction point is removing fluids from thehuman body.

The medical device contains a multi-balloon inflator that includes aplurality of connections, wherein at least one connection of themulti-balloon inflator contains radioactive isotopes while the remainingone or more connections of the multi-balloon inflator contain air or anyother liquid, such as a liquid saline solution, for inflation of thecorresponding balloon.

The medical device that contains a plurality of catheters can beinserted into both the rectum and the urethra with a plurality ofmeasuring devices to take dose measurements while applying dose therapythrough the multi-balloon inflator.

According to another general aspect, there is a method of operating amulti-functional catheter, wherein said method comprises connecting aplurality of catheters, inflating multiple balloons on a singlecatheter, removing human fluids from the human body, and pumping liquidsaline solution or radioactive isotopes into said multi-ballooninflator.

The connecting includes affixing any male or female connection to thecatheter.

The inflating is provided to each individual connecting point to allowthe volume for inflation.

The affixing to another catheter creates a vacuum seal that does notallow the fluids or any air to pass through any said connecting point.

The removing fluids by an inner seal within the opening that only allowsfor a single direction flow for only removal of fluids which does notallow for fluids to be inserted into the human body.

The removing includes a measuring device used to measure the amount ofdose radiated to human tissue while the extraction point is removingbodily fluids, such as from the human body.

The radiating includes providing by a multi-balloon inflator through acorresponding connection radioactive isotopes, while the other one ormore of the connections of the multi-balloon inflator contains air orany other liquid, such as a liquid saline solution, for inflation of thecorresponding balloon on a medical device that contains a multi-ballooninflator having a plurality of connections.

A plurality of said medical devices can be inserted into both the rectumand urethra with a plurality of said measuring devices take dosemeasurements while applying dose therapy through said multi-ballooninflator.

DETAILED DESCRIPTION

The following detailed description is provided to assist the reader ingaining a comprehensive understanding of the methods, apparatuses and/orsystems described herein. Accordingly, various changes, modifications,and equivalents of the systems, apparatuses, and/or methods describedherein will likely suggest themselves to those of ordinary skill in theart. Also, descriptions of well-known functions and constructions areomitted to increase clarity and conciseness.

FIG. 1 shows an exemplary medical device including a rectum catheter1-11 that includes a first position rectum balloon 1-2, as well as aballoon inflator 1-20 having connections 1-7 and 1-8; the rectumcatheter 1-11 being attached to a urethra catheter 1-10, the urethracatheter 1-10 including a urethra catheter balloon 1-1, as well as aballoon inflator 1-30 having connections 1-5 and 1-6. The rectumcatheter 1-11 that includes the rectum balloon 1-2 has multiple uses andfeatures. The rectum balloon 1-2 can be used to deliver radiation, suchas by radioactive isotopes that can be inserted via the connection 1-7,and a measuring device, e.g., a sensor, (not shown in FIG. 1), as can beassociated with the rectum catheter 1-11 or with the urethra catheter1-10, that can simultaneously measure the radiation that is beingdelivered to the abnormal growth and a connection of the rectum catheter1-11 can remove bodily fluids, e.g., human waste. The rectum catheter1-11 has a female or a male connection 1-8 of a balloon inflator 1-20that is used to insert any form of a sensor for dose measurement andsimultaneously remove human waste by an extraction opening 1-12 in therectum catheter 1-11. The extraction opening 1-12 contains an inner seal1-17 that only allows for a single direction flow for removal of bodilyfluids and does not allow for fluids to be inserted into a body cavity,such as the rectum. The human waste removed travels through a tube 1-3that is associated with the male or female connection 1-8. Furthermore,the rectum catheter 1-11 has a luer lock connection 1-7 of the ballooninflator 1-20 that is used to inflate the rectum balloon 1-2 to apredetermined size. The balloon inflation of the rectum balloon 1-2 maybe used as a locking mechanism for the rectum catheter 1-11 in thepatient or can be used to push internal organs in a certain direction.The rectum catheter 1-11 may be attached by a locking mechanism 1-9 tothe urethra catheter 1-10. The locking mechanism 1-9 may be attached byeither a male or a female connection, and the locking mechanism 1-9 isassociated with the balloon inflator 1-20 and the balloon inflator 1-30.The locking mechanism 1-9 allows for medical personnel to have an easiercontrol of the rectum catheter 1-11 and the urethra catheter 1-10 toprovide delivery and extraction guidance for the catheters within asingle area. The urethra catheter 1-10 has a urine or bodily fluidextraction opening 1-4 that communicates with a tube 1-15 that is usedto remove fluids in the bladder that are taken out by an extractionopening connection 1-5 of the balloon inflator 1-30 and by theassociated tube 1-15. The extraction opening 1-4 contains an inner seal1-18 that only allows for a single direction flow for removal of bodilyfluids and does not allow for fluids to be inserted into a body cavity,such as the bladder. Furthermore, a measuring device (not shown inFIG. 1) may be inserted into the extraction opening connection 1-5 andinto the tube 1-15 while removing the urine or bodily fluid. Theadvantage allows for simultaneously measuring a dose and removing urineby the urethra catheter 1-10. The urethra catheter balloon 1-1 is aninflatable balloon. The balloon inflation can be performed via a male ora female luer lock connection 1-6 of the balloon inflator 1-30 of theurethra catheter 1-10. Further drawings will show modifications to boththe urethra catheter 1-11 and the rectum catheter 1-10.

FIG. 2 shows an exemplary medical device, similar to that shown in FIG.1, including a rectum catheter 1-11 attached to a urethra catheter 1-10.Upon further review, the rectum catheter 1-11 allows for a measuringdevice 2-1 for dose measurement, such as a metal-oxide-semiconductorfield-effect transistor (MOSFET), to be inserted into a center valve ofa connection 1-8 of a balloon inflator 1-20 of the rectum catheter 1-11.The rectum catheter 1-11 may be attached by a locking mechanism 1-9 tothe urethra catheter 1-10, as described. The advantage for inserting themeasuring device 2-1 will allow medical personnel to measure the dosesimultaneously while delivering the radiation to the tumor region.Furthermore, a second measuring device 2-2 may be inserted into theurethra catheter 1-10 through an extraction opening connection 1-5 of aballoon inflator 1-30 and into an associated tube 1-15 of the extractionopening connection 1-5. Inflating the rectum balloon 1-2 allows fordetermining the organ region and for providing a fixing or lockingmechanism. The inflating rectum balloon 1-2 on the rectum catheter 1-11can also be filled with a radioactive material, e.g., radioactiveisotopes, via the connection 1-7 of the balloon inflator 1-20 thatdelivers dose while being measured by the measuring device 2-1. This isa big advantage since the dose can be measured and the volume ofradioactive isotopes can be reduced depending on the inflating size ofthe inflating rectum balloon 1-2. Next, the second measuring device 2-2can also be inserted into the urethra catheter 1-10 through theextraction opening connection 1-5 of the balloon inflator 1-30 into theassociated tube 1-15 and, along with the measuring device 2-1 in therectum catheter 1-11, can allow medical personnel to measure the dosefrom two different locations at the same time. Also, as described, theurethra catheter 1-10 has a urine extraction opening 1-4 thatcommunicates with the tube 1-15 and is used to remove fluids in thebladder that are taken out by the extraction opening connection 1-5 ofthe balloon inflator 1-30 and by the associated tube 1-15. Theextraction opening 1-4 contains an inner seal 1-18 that only allows fora single direction flow for removal of bodily fluids and does not allowfor fluids to be inserted into a body cavity, such as the bladder. Therectum catheter 1-11 has a female or a male connection 1-8 of a ballooninflator 1-20, that can be used to insert any form of a sensor for dosemeasurement and simultaneously remove human waste by an extractionopening 1-12 in the rectum catheter 1-11. The extraction opening 1-12contains an inner seal 1-17 that only allows for a single direction flowfor removal of bodily fluids and does not allow for fluids to beinserted into a body cavity, such as the rectum. The human waste removedtravels through a tube 1-3 associated with the male or female connection1-8.

FIG. 3 shows an exemplary medical device that includes a rectum catheter1-11 attached to a urethra catheter 1-10. The rectum catheter 1-11includes a first position rectum balloon 1-2 and second position rectumballoon 4-1, as well as a balloon inflator 1-20, as a multi-ballooninflator, having connections 1-7, 1-8 and 4-2; and the urethra catheter1-10 includes a first position urethra catheter balloon 1-1, as well asa balloon inflator 1-30 having connections 1-5 and 1-6. The rectumcatheter 1-11 may be attached by a locking mechanism 1-9 to the urethracatheter 1-10, as described. The rectum catheter 1-11 contains twoballoons, which allows for the first position rectum balloon 1-2 to beused for fixing or locking. The second position rectum balloon 4-1 canbe filled with a radioactive material, e.g. radioactive isotopes, viathe connection 4-2. The second position rectum balloon 4-1 can deliverthe radiation after the first position rectum balloon 1-2 has beeninflated via the connection 1-7. Another advantage for double inflatableballoons can be the first position rectum balloon 1-2 can be used tomove sensitive organs out of the region, and the second position rectumballoon 4-1 can deliver the dose. Each balloon has the ability to befilled up via its male or female connection. Specifically, the secondposition rectum balloon 4-1 is enlarged via the male/female connection4-2; and, the first position rectum balloon 1-2 is enlarged via themale/female connection 1-7. By allowing each balloon to have itsrespective connection, an advantage of such connection is that it willallow medical personnel to control the size of each balloonindependently. Also, as described, the urethra catheter 1-10 has a urineor bodily fluid extraction opening 1-4 that communicates with a tube1-15 that is used to remove fluids in the bladder that are taken out byan extraction opening connection 1-5 of the balloon inflator 1-30 andthe associated tube 1-15. The extraction opening 1-4 contains an innerseal 1-18 that only allows for a single direction flow for removal ofbodily fluids and does not allow for fluids to be inserted into a bodycavity, such as the bladder. The rectum catheter 1-11 has the female ora male connection 1-8 of the balloon inflator 1-20, that can be used toinsert any form of a sensor for dose measurement and while removinghuman waste by an extraction opening 1-12 in the rectum catheter 1-11.The extraction opening 1-12 contains an inner seal 1-17 that only allowsfor a single direction flow for removal of bodily fluids and does notallow for fluids to be inserted into a body cavity, such as the rectum.The human waste removed travels through a tube 1-3 associated with themale or female connection 1-8.

FIG. 4 shows an exemplary medical device, similar to that shown in FIG.3, that includes a rectum catheter 1-11 attached to a urethra catheter1-10. The rectum catheter 1-11 includes a first position rectum balloon1-2 and a second position rectum balloon 4-1, as well as a ballooninflator 1-20, as a multi-balloon inflator, having connections 1-7, 1-8and 4-2; and the urethra catheter 1-10 includes a first position urethracatheter balloon 1-1, as well as a balloon inflator 1-30 havingconnections 1-5 and 1-6. The rectum catheter 1-11 may be attached by alocking mechanism 1-9 to the urethra catheter 1-10, as described. Therectum catheter 1-11 contains two balloons. The second position rectumballoon 4-1 contains radioactive isotopes, provided via the connection4-2, while the first position rectum balloon 1-2 can contain air orliquid, such as a liquid saline solution, to fill the balloon via theconnection 1-7. The rectum catheter 1-11 contains a measuring device 5-1for dose measurement, as can be inserted through the connection 1-8 of aballoon inflator 1-20, similar to that previously described, that allowsfor measuring the dose that is applied to the patient. Next, a measuringdevice 5-2 for dose measurement, similar to that previously described,can also be inserted through an extraction opening connection 1-5 of aballoon inflator 1-30 and into an associated tube 1-15 of the urethracatheter 1-10, and along with the measuring device 5-1, as can beinserted through an extraction opening connection 1-8 of the ballooninflator 1-20 in the rectum catheter 1-11, can allow medical personnelto measure the dose from two different locations at the same time. Also,as described, the urethra catheter 1-10 has a urine or bodily fluidextraction opening 1-4 that is used to remove fluids in the bladder thatare taken out by the extraction opening connection 1-5 of the ballooninflator 1-30 and into the associated tube 1-15 of the extractionopening connection 1-5. The extraction opening 1-4 contains an innerseal 1-18 that only allows for a single direction flow for removal ofbodily fluids and does not allow for fluids to be inserted into a bodycavity, such as the bladder. The rectum catheter 1-11 has the female ora male connection 1-8 of the balloon inflator 1-20, that can be used toinsert any form of a sensor for dose measurement and simultaneouslyremove human waste by an extraction opening 1-12 in the rectum catheter1-11. The extraction opening 1-12 contains an inner seal 1-17 that onlyallows for a single direction flow for removal of bodily fluids and doesnot allow for fluids to be inserted into a body cavity, such as therectum. The human waste removed travels through a tube 1-3 associatedwith the male or female connection 1-8.

The urethra catheter 1-10 includes a first positionurethra catheter balloon 1-1, as well as a balloon inflator 1-30 havingconnections 1-5 and 1-6. The rectum catheter 1-11 includes a firstposition rectum balloon 1-2, a second position radiation balloon 4-1, athird position rectum balloon 7-1 and is attached to the urethracatheter 1-10, as well as including a balloon inflator 1-20, as amulti-balloon inflator 1-20, having connections 1-7, 1-8, 7-3 and 4-2.The rectum catheter 1-11 may be attached by a locking mechanism 1-9 tothe urethra catheter 1-10, as described. The rectum catheter 1-11 hasthree balloons 1-2, 4-1 and 7-1; however, there can be any number ofballoons, as can be spaced from each other on the catheter 1-11,depending upon the length of the catheter 1-11. The rectum catheter 1-11has the second position radiation balloon 4-1 that contains radioactiveisotopes, inserted via the connection 4-2, while the first positionrectum balloon 1-2 and the third position rectum balloon 7-1 may containno dose delivery mechanism. The first position rectum balloon 1-2 can beinflated via the male/female connection 1-7, and the second positionrectum balloon 4-1 can be inflated via the male/female connection 4-2.The third position rectum balloon 7-1 can be inflated via themale/female connection 7-3. Referring to FIG. 5B, an A-A view 7-2 of therectum catheter 1-11 provides a further illustration of when there are aplurality of balloons on a single catheter, such as the rectum catheter1-11. The A-A view 7-2 shows a cross-sectional view of the rectumcatheter 1-11 and the respective tubes, or connections, 4-2, 7-3, 1-7for inflating or deflating the respective balloons, as well as theconnection 1-8 that communicates with an opening 1-12. By havingmultiple balloons on a single catheter, the shape of each balloon can bechanged relative to the location of the catheter, such as the rectumcatheter 1-11, in the human body to allow for a proper fixture. Also, asdescribed, the urethra catheter 1-10 has a urine or bodily fluidextraction opening 1-4 associated with a tube 1-15 that is used toremove fluids in the bladder that are taken out by an extraction openingconnection 1-5 of the balloon inflator 1-30 and the associated tube1-15. The extraction opening 1-4 contains an inner seal 1-18 that onlyallows for a single direction flow for removal of bodily fluids and doesnot allow for fluids to be inserted into a body cavity, such as thebladder. The rectum catheter 1-11 has the female or a male connection1-8 of a balloon inflator 1-20, that can be used to insert any form of asensor for dose measurement and simultaneously remove human waste by theopening 1-12 in the rectum catheter 1-11. The extraction opening 1-12contains an inner seal 1-17 that only allows for a single direction flowfor removal of bodily fluids and does not allow for fluids to beinserted into a body cavity, such as the rectum. The human waste removedtravels through a tube 1-3 associated with the male or female connection1-8.

FIG. 6A shows an exemplary medical device, similar to that shown in FIG.5A, that includes a rectum catheter 1-11 attached to a urethra catheter1-10, as well as a balloon inflator 1-20, as a multi-balloon inflator,having connections 1-7, 1-8, 7-3 and 4-2. The urethra catheter 1-10includes a first position urethra catheter balloon 1-1, as well as aballoon inflator 1-30 having connections 1-5 and 1-6. The rectumcatheter 1-11 may be attached by a locking mechanism 1-9 to the urethracatheter 1-10, as described. The rectum catheter 1-11 includes acollapsed first position rectum balloon 1-2 as a collapsed balloon 8-1as can be inflated via the connection 1-7, a second position radiationballoon 4-1 as can be inflated or filled with a radioactive material,e.g. radioactive isotopes, via the connection 4-2 of the ballooninflator 1-20, and a third position rectum balloon 7-1 as can beinflated via the connection 7-3; and the balloons 1-2 (the collapsedballoon 8-1), 4-1 and 7-1 can be spaced from each other along the lengthof the catheter 1-11, such as illustrated in FIG. 6A. The collapsedballoon 8-1 allows for minimum expansion of the balloon, such as byinflation thereof via the connection 1-7, to keep the human tissue frombeing moved into any direction. Furthermore, a measuring device 8-2,similar to those previously described, can be inserted into an opensection (tube) 1-3 associated with the connection 1-8 in the rectumcatheter 1-11 of the balloon inflator 1-20. The benefit for havingmultiple balloons allows the control of how much dose can be given.Next, a measuring device 8-3, similar to those previously described, canalso be inserted into the urethra catheter 1-10 through an extractionopening connection 1-5 of the balloon inflator 1-30 and into anassociated tube 1-15 of the extraction opening connection 1-5, alongwith a measuring device 8-2, in the rectum catheter 1-11 to allowmedical personnel to measure the dose from two different locations atthe same time. Referring to FIG. 6B, an A-A view 7-2 of the rectumcatheter 1-11 provides a further illustration of when a plurality ofballoons are on a single catheter, such as the rectum catheter 1-11. TheA-A view 7-2 shows a cross-sectional view of the rectum catheter 1-11and the respective tubes, or connections, 4-2, 7-3, 1-7 for inflating ordeflating the respective balloons, as well as the connection 1-8 thatcommunicates with an extraction opening 1-12. By having multipleballoons on a single catheter, the shape of each balloon can be changedrelative to the location of the catheter, such as the rectum catheter1-11, in the human body to allow for a proper fixture. The advantage forhaving multiple balloons allows medical personnel to have more control.Also, as described, the urethra catheter 1-10 has a urine or bodilyfluid extraction opening 1-4 that is used to remove fluids in thebladder that are taken out by the extraction opening connection 1-5 ofthe balloon inflator 1-30 and by the associated tube 1-15. Theextraction opening 1-4 contains an inner seal 1-18 that only allows fora single direction flow for removal of bodily fluids and does not allowfor fluids to be inserted into a body cavity, such as the bladder. Therectum catheter 1-11 has the female or a male connection 1-8 of theballoon inflator 1-20, that can be used to insert any form of a sensorfor dose measurement and simultaneously remove human waste by theextraction opening 1-12 in the rectum catheter 1-11. The extractionopening 1-12 contains an inner seal 1-17 that only allows for a singledirection flow for removal of bodily fluids and does not allow forfluids to be inserted into a body cavity, such as the rectum. The humanwaste removed travels through a tube 1-3 associated with the male orfemale connection 1-8.

FIG. 7 is an illustration of how both a urethra catheter 10-1 and arectum catheter 10-6 are inserted into the human body. The urethracatheter 10-1 is inserted into the penis via the urethra. Thereafter,the medical personnel inflates a balloon 10-2 on the urethra catheter10-1. This will allow the surrounding tissue to expand and move out ofthe way to create space near the prostate 10-5. Furthermore, the rectumcatheter 10-6 can be inserted into the rectum of the patient. The rectumcatheter 10-6 has a first position rectum balloon 10-3 and a secondposition rectum balloon 10-4. Looking specifically at this illustrationof FIG. 7, but not limiting it to just the second position rectumballoon 10-4, the second position rectum balloon 10-4 containsradioactive isotopes. This can be used to dose the prostate 10-5, andthe first position rectum balloon 10-3 can be used as a locking orfixing mechanism to the hold the rectum catheter 10-6 in place.Furthermore, a measuring device for dose measurement, similar to thosepreviously described, can be inserted into both the urethra catheter10-1 and the rectum catheter 10-6.

FIG. 8 is another illustration of how both the urethra catheter 10-1 andthe rectum catheter 10-6 are inserted into the human body. The urethracatheter 10-1 is inserted all the way into the male bladder and inflatedwith a balloon 11-1. The inflation of the balloon 11-1 will not allowfor the urethra catheter 10-1 to slip out of the bladder. Furthermore,the rectum catheter 10-6 has a first position rectum balloon 10-3 and asecond position rectum balloon 10-4. Looking specifically at thisillustration of FIG. 8, but not limiting it to just the second positionrectum balloon 10-4, the second position rectum balloon 10-4 containsradioactive isotopes. This second position rectum balloon 10-4 can beused to dose the prostate 10-5, and the first position rectum balloon10-3 can be used as a locking or fixing mechanism to hold the rectumcatheter 10-6 in place. Furthermore, a measuring device for dosemeasurement, similar to those previously described, can be inserted intoboth the urethra catheter 10-1 and the rectum catheter 10-6.
